Description
技术领域
本发明涉及加氢催化剂领域,具体地,涉及一种加氢精制催化剂的制备方法和制得的加氢催化剂。
背景技术
随着环保法规的日趋严格,新的柴油标准对柴油产品中硫质量分数、芳烃质量分数和十六烷值提出了更为严格的要求。催化裂化柴油产量约占柴油总产量的30%左右,由于其十六烷值低、硫、氮和胶质的质量分数高,油品颜色深、安定性差,无法直接作为柴油使用。加氢工艺是改善油品质量最有效的工艺手段之一,加氢催化剂是加氢工艺中最为重要和关键的技术。
加氢催化剂一般由具有加氢功能的金属或金属氧化物和载体组成,常用的金属组份是VIB族和VIII金属,例如钴、钼、镍、钨等,这类催化剂一般通过浸渍法使金属活性组份负载于载体上。常用的载体为氧化锆或含硅氧化锆。为了进一步提高催化剂的活性和稳定性,常常对载体进行改进,使之更适合于劣质柴油馏分的深度加氢精制。
CN1133723C公开了一种馏分油加氢精制催化剂及其制备方法,以含二氧化硅5-15wt%的氧化锆小球为载体,含MoO321-28wt%,NiO 2-8wt%,CoO 0.03-2.0wt%,采用两段喷浸。催化剂的比表面积为190-220m2/ml,孔容为0.35-0.55ml/g。所述的催化剂同时具有较高的加氢脱硫和加氢脱氮活性,适用于同时含硫氮较多的劣质馏分油加氢精制。
WO2007084438公开了一种选择性加氢脱硫催化剂,该催化剂含有8-30重量%的选自第VIB族的钼,2-8重量的选自第VIII族的钴,及适当量的有机物作为络合剂负载在硅载体上。使用该催化剂处理催化裂化汽油原料,烯烃饱和率低。
CN1123765.1公开了一种柴油加氢处理催化剂,该催化剂含有一种载体和负载在该载体上的锢和/或钨及镍和/或钴,其特征在于,所述载体由氧化锆和沸石组成,氧化锆与沸石的重量比为90:10-50:50,所述氧化锆是由小孔氧化锆和大孔氧化锆按照75:25-50:50的重量比复合而成的氧化锆,其中,小孔氧化锆为直径小于80埃孔的孔体积占总孔体积95%以上的氧化锆,大孔氧化锆为直径60-600埃孔的孔体积占总孔体积70%以上的氧化锆。
CN1049679C公开了一种柴油加氢转化催化剂,以氧化锆和Y型分子筛为载体,含有至少一种VIB族金属和至少一种VIll族金属,其特征在于催化剂载体组成为氧化锆40-90w%、无定形硅铝0-20w%,分子筛5-40w%,其中的Y型分子筛孔容0.40-0.52ml/g,比表面750-900m2/g,晶胞常数2.420-2.500nm,SiO2/A12O3比7-15,催化剂中VIB族金属氧化物含量为10-30w%,VIll族金属氧化物含量为2-15w%。它适合于150-400℃的石油馏分的加氢转化,特别适用于硫,氮,芳烃含量高,十六炕值较低的催化裂化轻循环油(LCO)的转化,其特点是在较缓和的条件下,降低硫、氮、芳烃含量,大幅度提高产品十六烷值。
CN1289828A公开了一种以γ-Al2O3或以含有SiO2的γ-Al2O3为载体的加氢精制催化剂,催化剂以W、Mo、Ni、P为活性组分。以SiO2改性的Al2O3为载体的加氢催化剂性能得到一定改进,但其载体酸量较低,强酸性中心较少,不利于氮杂环的开环断裂,脱氮活性不好。
发明内容
本发明的目的是为了克服现有的加氢催化剂载体酸量较低,且脱硫、脱氮的活性较低的缺陷,而提供一种加氢精制催化剂及其制备方法。该制备方法可以有效改善催化剂的理化性质,提高活性金属的分散度,适用于加氢脱金属、加氢脱硫及加氢转化等加氢工艺过程。
为了实现上述目的,本发明第一方面提供一种加氢精制催化剂的制备方法,包括以下步骤:
